NBN outage - quick way to connect online?

hello everyone,I would like to share a bad experience with TPG after an electricity outage that happened two days ago. After which no internet connection was possible. When calling TPG and after an hour on the phone waiting, I was suggested to buy a new modem without any verification.I'm leaving overseas in two weeks so it didn't make sense for me to buy a expensive modem for two weeks but TPG couldn't care less as I'm leaving the country, even if I have been a costumer for 5 years. They refused to lend or provide even a used modem for 2 weeks.I bought a modem, installed it and still the same issue. I recalled TPG support for again another hour on the phone to discover what? the issue wasn't the modem but NBN connection and they have escalated it to NBN to send a technician.I've lost one day on the phone and money buying a new modem.My work depends on internet.Is there a way to connect online? a cheap quick way to have a connection on my laptop?my phone is on TPG but the connection is very bad even if I live in Sydney. I can't rely on it.Please, any suggestion is more than welcome .thank you
